Direct ink writing of high-resolution cellulose structures
Three-dimensional (3D) printing has a significant role in membrane production for water purification and bio-separation, with capacity to create new and cleverly designed structures. Among the available 3D printing methods, the strategy of direct ink writing offers a process to print a wide variety of materials with high resolution. In a new report now published on Scientific Reports, Farnaz Rezaei and a team of researchers at the Uppsala University Sweden, used cellulose acetate as a biocompatible ink material. The researchers noted the printability and possibility of printing features as small as a few micrometers to examine the development of cellulose acetate with varying molecular weights. The nozzle's internal and external diameters affected the detailed resolution of the printed structure. The researchers used different inks to result in different widths of printed strands and successfully completed direct writing with high-resolution cellulose structures.

Industry has long relied upon energy-intensive processes, such as distillation and crystallization, to separate molecules that ultimately serve as ingredients in medicine, chemicals and other products. In recent decades, there has been a push to supplant these processes with membranes, which are potentially a lower-cost and eco-friendly alternative.

My very first paper as the last corresponding author was just accepted today!
Coincidentally, today is also exatly 5 years since I sent my PhD thesis to print before the defence.

Me and my mate are on a roll! Membranes is a bizarre 90s post-apocalyptic queer Tawainese sci-fi romp. It’s taken two false starts to really get into, but now I’m in. The translator end notes are also a delight!

'Plug-and-Play' Nanoparticles Could Make it Easier to Tackle Various Biological Targets - Technology Org
New Post has been published on https://thedigitalinsider.com/plug-and-play-nanoparticles-could-make-it-easier-to-tackle-various-biological-targets-technology-org/
'Plug-and-Play' Nanoparticles Could Make it Easier to Tackle Various Biological Targets - Technology Org
Researchers at UC San Diego have developed modular nanoparticles that can be customized to target biological entities such as tumors, viruses or toxins.
The surfaces of the nanoparticles are engineered to host biological molecules, making it possible to tailor the nanoparticles for applications from targeted drug delivery to neutralizing biological agents.

Scientists say the beauty of the technology lies in its simplicity and efficiency. Researchers can use a modular nanoparticle base to attach proteins targeting a desired biological entity rather than crafting new nanoparticles for each specific application.
In the past, creating nanoparticles for different biological targets required going through a distinct synthetic process from start to finish each time. But with this new technique, the same modular nanoparticle base can be modified to create a set of specialized nanoparticles.
“This is a plug-and-play platform technology that allows for rapid modification of a functional biological nanoparticle,” said Liangfang Zhang, a nanoengineer at UC San Diego.
Zhang and his team detail their work in a U.S. National Science Foundation-supported paper published in Nature Nanotechnology.
The modular nanoparticles consist of biodegradable polymer cores coated with genetically modified cell membranes. The key to the design is a pair of synthetic proteins, known as SpyCatcher and SpyTag, that are designed to spontaneously — and exclusively — bind with each other. This pair is commonly used in biological research to combine various proteins. In this study, Zhang and his team harnessed the pair to create a system for attaching proteins to a nanoparticle surface with ease.
Here’s how it works: SpyCatcher is embedded onto the nanoparticle surface, while SpyTag is chemically linked to a protein, such as one targeting tumors or viruses. When SpyTag-linked proteins encounter SpyCatcher-decorated nanoparticles, they bind to each other, enabling proteins of interest to attach to nanoparticle surfaces. 
For example, to target tumors, SpyTag can be linked to a protein designed to seek out tumor cells. That SpyTag-linked protein is then attached to the nanoparticle. If the target shifts to a specific virus, the process is similar: Link SpyTag to a protein targeting the virus and attach it to the nanoparticle surface.
“It’s a streamlined and straightforward approach to functionalizing nanoparticles for any biological application,” said Zhang. The researchers are looking to further improve the modular nanoparticle platform for targeted drug delivery.

"The funniest thing about Invader Zim is" no, the funniest thing about Invader Zim is Jhonen Vazquez's repeated insistence that Gaz was intended to be the normie sibling to Dib's baby's-first-cybergoth and that he genuinely never intended her to read as goth herself.

A non-invasive way to turn a cockroach into a cyborg
A team of mechanical engineers at Nanyang Technological University in Singapore has found a way to electronically control cockroaches without injuring them. In their paper published in the journal npj Flexible Electronics, the group describes the new technology they used to remotely control the cockroaches and the benefits of doing so. Prior research teams have created a variety of cyborg cockroaches, but they all had one feature in common—they all involved attaching probes to the insect's nervous system—procedures that led to damage to the insect, and likely some degree of pain. In this new effort, the researchers noted that damaging cockroaches during attempts to control them results in a very short life expectancy, which then results in very little payoff for a lot of work. They also suggest such research is unethical because of the pain inflicted on the cockroaches. In this new effort, they have found a way to control cockroaches that does not involve cutting into them, resulting in a much longer lifespan.
